Story

The narrative of this ancient life

Region & Environment

Georgia sits at the crossroads of mountain and lowland habitats, with access to varied resources. During the early Upper Paleolithic, local climates were cooler and landscapes would have shifted repeatedly, influencing the distribution of game and the availability of plant foods.

Historical Context

Dzudzuana Cave Culture belongs to the early Upper Paleolithic of the Caucasus region. In this period, human groups in the region relied on stone tool technologies and mobile foraging systems, using caves and rock shelters as favorable locations.

Populations & Lifeways

Populations were hunter-gatherers with flexible mobility. Life revolved around procuring wild resources and processing them on-site, with activities organized around tool production, maintenance, and the repeated use of sheltered locations during favorable hunting seasons.

Archaeology & Material Culture

Archaeological work in caves such as Dzudzuana typically yields dense concentrations of lithic artifacts associated with flaking and tool use. The stratified deposits can preserve sequences of occupation, allowing archaeologists to recognize changing toolkits or activity emphases over time. Where organic remains are preserved, they can supplement lithic evidence, though preservation varies.

Culture & Society

Cultural practice is most visible through recurring stone-tool traditions, including characteristic reduction methods and tool forms. These patterns imply learned techniques passed within groups and possibly shared across neighboring populations, reinforcing cultural cohesion in a wider Paleolithic world.

Legacy & Transition

Over time, climatic fluctuation and changing ecosystems influenced how Paleolithic groups used landscapes and shelters. Dzudzuana contributes to the deep archaeological sequence that helps track the long-term development of hunter-gatherer lifeways in the Caucasus before later Mesolithic and Neolithic transitions.

Three assays for in-solution enrichment of ancient human DNA at more than a million SNPs

Authors Rohland N, Mallick S, Mah M, Maier R, Patterson N et al.
Abstract

The strategy of in-solution enrichment for hundreds of thousands of single-nucleotide polymorphisms (SNPs) has been used to analyze >70% of individuals with genome-scale ancient DNA published to date. This approach makes it economical to study ancient samples with low proportions of human DNA and increases the rate of conversion of sampled remains into interpretable data. So far, nearly all such data have been generated using a set of bait sequences targeting about 1.24 million SNPs (the "1240k reagent"), but synthesis of the reagent has been cost-effective for only a few laboratories. In 2021, two companies, Daicel Arbor Biosciences and Twist Bioscience, made available assays that target the same core set of SNPs along with supplementary content. We test all three assays on a common set of 27 ancient DNA libraries and show that all three are effective at enriching many hundreds of thousands of SNPs. For all assays, one round of enrichment produces data that are as useful as two. In our testing, the "Twist Ancient DNA" assay produces the highest coverages, greatest uniformity on targeted positions, and almost no bias toward enriching one allele more than another relative to shotgun sequencing. We also identify hundreds of thousands of targeted SNPs for which there is minimal allelic bias when comparing 1240k data to either shotgun or Twist data. This facilitates coanalysis of the large data sets that have been generated using 1240k and Twist capture, as well as shotgun sequencing approaches.
